earner ol -rue T messiah-see,- 1909-1" Application filed November 2'7,1908. Serial No. 46%,532.

To all whomtt may concern:

-Be it known that I, Minus H. MANN, a citizen of the United States,residing at Louisiana, Missouri, have invented a certain new and usefulImprovementin Ice-Picks, of which thefollowing is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, formic g part ofthis specification, in. which-Figure 1 is an elevational view, partly in vertical section, of anice-pick constructed in accordance with my invention; and Fig. 2

is a cross sectional view taken approximately on the line 22 of Fig. 1,looking in the direction of the arrow.

This invention relates to icepieks, and particularly. to that type whichcomprise a sharp-pointed pick or shank and a heavy handle or headreciprocating-1y mounted on the upper end of said shank and adapted tobeused as a striking member to force the pointed end of the shank into theice.

The main object of my invention is to provide an ice-pick of simpleconstruction that is strong and which can be manuiae tured at alow cost.

Referring to the drawings which illustrate the preferred form of myinvention, 1 designates a round shank having a sharppointed end, anddesignates a handle or head that is reciprocatingly mounted on the upperend of said shank. T he head 2 is pro Vided with a socket 3 into whichthe upper end of the shank projects, and below said socket is alongitudinally ext-ending bore 4; of greater diameter than the socket 8.coiled spring 5 surrounds the portion of the shank 1 thatentends'through said bore, and the upper and lower ends of said springbear against the upper end wall of the bore -land a cross pin 6 on theshank. The shank l is held in position by i'neans eta not 7 that screwedinto the lower end of the bore 1-, and a washer 8 is arranged betweenthe inner face of the nut T and the cross pin 6,

In operation, the head 2 is moved downwardly on the shank so that. theupper end wall 3 of the socket 3 will come in contactwith the upper endface oi; the shank and thus impart a blow to the shank that will forceit into the-ice, the spring 5 operating to restore the head to its.uorinal elevated position.

An ice-pick of the construction above described comprises l'ew parts andcan be maiuiluctured at a low cost, and as the head 2 acts directly onthe end oi? the shank 1 instead of on a pin or other separate piececonnected to the shank, the device is very strong and can be used for u.long period without wearing out or becoming broken.

While I have stated that the tool herein shown is adapted to be used asan ice-pick I ish itto be understood that it could be used for variousother purposes, such, for example, as a prick punclnnnd therefore myinvention is not limited to an ice-pick or a tool for splitting orliircuking ice.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An ice-pick conmrisiiig a heavy head having a longitudinallyextending bore and a socket of less diameter than the bore and locatedat the inner end thereof, a shank on which said head is rcciprocatinglymounted, the upper end of said shank being adapted to contact with theend wall of said socket when the head is moved downwardly on the shank,a coiled spring surrounding said shank and arranged between a shoulderunnged in said bore and surrounding said shank, a cross pin on saidshank which con- RANK. w. w en, olifi iiQllISIiilX'gi.
